Oracle 12c: Lateral, row_limiting_clause

Previously i showed how we can optimize getting TopN rows sorted by field “B” for each distinct value “A” with undocumented “lateral” in previous versions of Oracle RDBMS.
But now it is documented!
Very simple example:

with t as (select level a from dual connect by level<=10)
select *
from t
,lateral(
select *
from dba_objects o
where object_id=t.a
)
;
